Features ​Pressure regulator turns high pressure gas into low pressure gas, and keep the output gas pressure and flows rate stable. The oxygen pressure regulator can reduce, display and stabilize pressure; when inlet pressure and outlet flows change, it can guarantee the stability of outlet pressure. Compact structure, pressure gauge and high pressure gauge are made of high quality material, overall compact structure, perfect, good sealing. This oxygen pressure reducer is mainly used for gas welding, agricultural plant culture, chemical industry and so on. High quality full copper body, pressure regulation is stable, safe and reliable.
